According to the Census of Fatal Occupational Injuries, the
number of fatal work injuries decreased by 8% in the
United States (U.S.) from 5,657 in 2007 to 5,214 in 2008.
However, in Oklahoma, the number of fatal work injuries
increased by 16% from 105 in 2007 to 122 in 2008.
Overall, the Oklahoma rate of fatal work injuries was 60%
higher than the U.S. rate (2007: 6.4 and 4.0; 2008: 6.1 and
3.7 per 100,000 full-time equivalent workers) partly due to
the high number of fatalities of out-of-state workers
traveling through Oklahoma. Transportation-related
incidents were responsible for more than half of the
fatalities among workers in 2007 and 2008.
• A total of 70 motor vehicle crashes on public roadways
were responsible for 77 work-related deaths in
Oklahoma in 2007 and 2008.
• Ninety-five percent of workers were male (Figure 1).
– Sixty-one percent were 30-59 years of age with the
highest number of fatalities among workers 50-59
years old.
• Victims included drivers (78%), passengers (12%),
pedestrians (7%), and train conductors (3%).
– Three highway maintenance pedestrians were killed
while working in a work zone area.
• Nearly all deaths (94%) occurred on the day of the
incident; five workers were hospitalized before they
expired.
• Causes of death were multiple blunt force body injuries
(41%); multiple head, neck, and chest injuries (27%);
complications of burns (16%); head injuries (10%); and
suffocation (5%).
• The most common industries included
transportation/delivery (48%), oil and gas (16%), and
construction (9%).
• Seventy-one percent of fatal injuries involved large
trucks/tractor-trailer trucks (most more than 26,000
pounds).
– 50 workers killed in these crashes were truck drivers
by occupation; of these, 43 persons were driving at
the time of the crash.
– 39 crashes involved commercial motor vehicles
(CMV); 67% had five axles and 59% were interstate
CMV.
– Thirty-three percent of fatal work-related crashes
involving large trucks/tractor-trailer trucks were out-of-
state carriers.
• Twenty-one percent of crashes involved light trucks, which
included pickup trucks, sport utility vehicles, and vans.
– The most common occupations of these workers
included sales/services, oil field, construction, and
government.
• The majority of crashes occurred in rural areas (88%),
on high speed (65-75 miles/hour) roadways (76%), and
on state or U.S. highways (74%).
• Information on seat belt use was known for 47 vehicle
occupants. Of these, 62% were not wearing a seat belt.
Drivers of large trucks were more likely to be unbelted
than drivers of other vehicles.
– The percent of seat belt use among vehicle
occupants who died in work-related traffic crashes
was much lower than the statewide seat belt usage
rates (83.1% in 2007 and 84.3% in 2008).
• Five workers were alcohol impaired and one was drug
impaired at the time of the crash.
• The most common contributing causes of crashes included
unsafe or excessive speed for traffic/road conditions (35%),
driver inattention/sleepiness (18%), driving left of center of
roadway (13%), and failure to stop for traffic signals (13%).
